The correct option is D Rs.13,60,000
Selling price is 125% of the purchase price. This means if a sale is 125 then cost is 100.
Total sales for the June 2015=15,00,000+2,00,000=17,00,000
Cost of goods sold =17,00,000×100/125=13,60,000.
Opening stock +Purchases−Closing stock= Cost of goods sold
4,08,000+x−4,34,400=13,60,000
x=Purchases=13,86,400.
